Well in Jessica Jones I wondered why she didn't mention the Avengers' names. In one episode she says "Green Guy" and "Flag Waver" not Hulk and Captain America and it IS a Marvel Studios production unless it has to do with some rights to ABC.
It also goes back to Daredevil season one. Only Captain America is mentioned by name. If you remember, Wesley says "playboy billionaire in an Iron suit and a man with a giant hammer."
The Netflix shows and Agents of SHIELD are produced by ABC Studios and by Jeph Loeb.
Loeb says that "it's all connected" but there has been zero legitimate evidence of that and "Green Guy," "Flag Bearer," "Playboy Billionaire" and "Man with giant Hammer" is not legit evidence. Legit evidence would actually be mentioning the Avengers by name....Captain America, The Hulk, Thor, Iron Man.
Yet with Agents of SHIELD, the MCU references are everywhere. Not so much for season three, although Coulson did name drop "Pym" in the season premiere I think. There's also still HYDRA, who I think remains a key player in Cap: Civil War with Crossbones and Zemo.
If Luke Cage, Iron Fist and Defenders continues on without mentioning a single MCU character by their names, the chances of seeing Charlie Cox, Krysten Ritter, Mike Colter, Jon Bernthal (if he survives Daredevil Season 2), Elodie Yung, Rachael Taylor, Simone Missick and whoever they cast as Iron Fist even in cameos (ie a news report about the Defenders fighting Thanos' forces on the ground because we'll know he'll have ground forces) for the next two Avengers movies, chances are there is a 0% chance of seeing any of them, even in cameos via the news report I mentioned. I don't think time is running out, but I think time is tight. The ground forces for the next two Avengers movies will not be any of the heroes introduced via Netflix in cameos. I can see the ground forces being these guys:
Nick Fury:

Maria Hill:
Falcon:
The Winter Soldier:
War Machine:
Black Panther:
Ant Man:
Wasp:
Sharon Carter:
Dr. Strange:
And of course, Spider-Man
And if any team cameos via that news report, it'll probably be the Secret Warriors.
I think Carol will be fighting Thanos' forces in the air (ie. Cosmos).
